CAR-COU PLI NG.

SPECIFICATION forming part 0f Letters Patent No. 506,287, dated October 10, 1893.

Application filed .Tune 13, 1893. Serial No. 477,463. (No model.)

To all whom it may concern,.-

Beit knownthat I, JOSEPH WADLEIGH, a citizen of the United States, residing at Milks Grove, county of Iroquois, (post-office address Herscher, Kankakee oounty,) State of Illinois, have invented new and useful Improvements in Car-Couplers, of which the following is a complete specification, reference being had to the annexed drawings, illustrating the invention, in which- Figure 1, is a plan, or top view ot' the coupling with the draw-bars locked and in position as when a train of cars is to be moved, a portion of the platform` timbers being removed, more clearly to show the devices; Fig. 2, a side elevation of Fig. l, and asection -of the supporting timbers; Fig. 3, the two drawbars in plan view, removed more clearly to show their construction; Fig. 4, an end view of the buffer portion of onev coupler frame; Fig. 5, a transverse section ot' Fig. 2 on line y; Fig. 6, an elevation of one of the drawbars shown at Fig. 3.

The novelty, construction and operation of this invention will be fully comprehended by the following detail description.

A, B, represent the two hollow frame supports in which the draw-bars C, D, operate. These frames are supported by the ordinary timbers E, E, of the car platform in the ordinary manner, said timbers being shown by dotted lines at Fig. l, and in section at Fig.

2. The butter portion G, G, are nearly square in face view, thereby permitting a considerable downwardly inclinedposition to the lock-ends H, of the draw-bars C, D. In opposite sides of both frames A andB are formed slots 1,1, on the lines of screw paths, and each slot registers nearly forty-five degrees of the cylindrical portions of the said frames. Two pins J, are inserted in the shank portions of both draw-bars and the pins projectinto the slots I, and are guided thereby to turn each draw-bar about one fourth round during the locking process. An Ordinary pin K, by means of a hole L in each frame A, B, drops into each hole X when the buers G meet.

One draw-bar may be pinned fast to its frame,

A spring N, is placed` inleach frame A, B,and by means of pistons S,placed between the springs and the ends of the draw-bars, the projections P, P,- ,which compose portionsl of the lock will, by contact of the lock ends of the draw-bars pass back into the buer ends of the frames A, B, as shown by dotted lines Fig. 1; and thus the draw-bars may come together with'a yielding force; a rod T to each piston, passing through a timber R, and secured by a nut, permits the springs to be compressed, but prevents the expansion of the spring beyond agiven point which will permit the portions P, P to project their respective thicknesses beyond the buffers G, G. O, 0,' &c., are straight slots and continuations of the slots I, and permit of the movementback of the curved slots. Each buffer G is recessed in at its under side at Q `freely to permit the draw-bars to slide downward and'out of the frames; and so as not to -be'` in the way of their movement into the frames.

Forthe convenience of using on one car one of my couplers and a link coupler of the ordinary kind on another car, mortisesV are formed in the portions H and holes a, are also formed in them to receive the ordinary pins. The frames A, B, are to be secured to the timbers E, E, by straps and bolts of such ordinary constructiony .as to require no description.

The operation is simple; the locks H, H, in forcible contact pass into the frames and in so doing are turned by means of the slots I and pins J, and the locks H are broughtinto the recesses W, and at the proper time the pins K fall into the holes kX. The said pins, may if desired be operated by levers to obviate the necessity of a'person going between the cars.

Having thus described my invention, I

claim and desire to secure by Letters Patent of the United States- An improvement in car couplers consisting of two cylindrical draw-bar frames with notched buffers at their face portions, and provided each in their opposite cylindrical portions withspiral slots and short straight slots which are continuations of thespiral slots, in combination with two draw-bars, -whichfare provided with two opposite pins IOO engaging and operatingin said slots,a,nd each au expansion and compression equal to the draw-bar provided with a hook and recess at length of the short, stralght slot; as and for lts locking end, said bars each having a parthe purpose specified.

tial rotary motion in its movement in the JOSEPH VADLEIGII. 5 frame supports, and the hook of each drawlVitnesses:

bar engaging the recess in the other bar, and G. L. CHAPIN,

a spring at the back end of each bal', having HERMAN HOFF.
